Power, on demand, as you need it

Reviewed in the United States on January 14, 2015

Verified Purchase

A bit of personal background, I'm a technical professional with over 40 years in information services (hardware / software). I generally don't get excited about a maker unless there is something that makes their products unusual or otherwise special. Anker is one of those makers. Disclaimer: I have been so impressed with the quality of build and usability of design that I Anker makes what I am looking for, that's what I will buy.

I bought this battery / charger because my prior (earlier) model got legs on a business trip. Since my set of mobile devices has grown a bit, I decided to go with a bit larger setup. That lead to the 16000mAh model. My primary use is keeping devices charged / operating on coast to coast flights, and next as an emergency battery/charger when I forget to plug in as needed. So far it's been quite capable of powering a Samsung Tab 3 and Note 3 on 5+ hour flights. I don't have any practical basis for estimating how long it would continue as it still indicates at least 50% capacity at the end of the trip.

It's not just the technical capability, but the design and build quality are also excellent. It has a great finish, the iQ power means you don't have to worry which port to use. And the LED is a nice convenience. For my money this is one of the best battery/charger packs you can own.

Trick like using shorter cables for lowering the losses of current

Reviewed in the United States on March 17, 2016

Verified Purchase

I was thinking about second battery for my phone, but this tool is more versatile, cause you can charge practically every electronic device on 5V and with micro-usb connector (or if you have adapters every other). So far Ive only recharged twice and can not say accurately the charging capacity although I feel it's not 15000 mAh but less. Unless there's some trick when charging. Trick like using shorter cables for lowering the losses of current.

other issue I have is when I'm charging the device I don't know when it is fully charged (the manual says you need to remove from AC when fully charged to extend battery life). Is it fully charged when 3 LEDs are lit and 4th is blinking or I need to wait for the 4 LEDs to be lit. If i remove the cable the 4 are lit but if i put back to charge the 4th LED start blinking.

So I think it would be nice if the device had a small screen to show the battery level in % to be clearer what's the level of charge in the device (which is the most importan characteristict).

I don`t know if it's better to charge the device on 1A or 2A port (if you have enough time to wait for the slower, lower chage) better for the charger, better for the charged device

I bought a superior USB rechargeable battery

Reviewed in the United States on June 19, 2019

Verified Purchase

I do not understand why the review interface is presenting me with a photo of a woman using a cosmetic face mask from a tube. I bought an electronic device. My Anker portable battery charger described in the text portion is still working like it did out of the box after hundreds of cycles. I only wish it were waterproof/shockproof. I keep it protected from water at all times, and have never dropped it. Four years and about two thousand miles on the bicycle/ hundreds of days in the backpack with me and it's still going strong. I have other Anker products. This brand satisfies.

I bought this 4 years ago. Today is (4/10/20) Charges iPhone 8 five full times on one charge. Takes usually 6 hours to fully recharge. The only thing that failed was one of the USB ports is loose and will not charge unless pressure is put to one side. This has been in my truck in the cold and heat. Transported with me in many trips. Will buy again. Solid!

Well Done, Anker

Reviewed in the United States on September 3, 2016

Verified Purchase

I am truly impressed. This a good external battery. It packs a punch.
I started playing Pokemon Go, like most; and as a child, I watched the show. I even remember watching the Pokemon movie when I was a kid.
Anyway, if you played the Pokemon app, you should know that this game will kill your battery. That's when this product comes in handy. When I'm out walking I carry this battery block with me.
Pros
-extra battery power
-charges the iphone 6 (6 times)
-2 USB ports
-has built in flashlight
-Portable
Cons
-long charging duration of device
-blue light of display hurts my eyes
-bulky
Although, I have some minor issues with this Anker product, I am still content with my purchase.

I'll be sticking with Powercore for two key reasons...

Reviewed in the United States on September 25, 2016

Verified Purchase

I have the Powercore 20100 and love the thing. I thought I was buying a slightly lower capacity unit that would act the same, but it doesn't.

On the Powercore, when I disconnect the device that's charging accidentally, I get a few seconds to reconnect it before the device turns off. This one turns off right away.

That wouldn't be such a bad thing, and on the power core if I need to turn the unit back on I can just reach in my pocket and press the button without looking and turn it on.

It turns out that this model has a light in it. So one cycle of the button turns it on, another turns the light on & off. So I found that I was constantly having to fiddle with it to turn it back on because it both turns off so quickly and because it's not a straight & simple on/off.

If you haven't had something more convenient than this one or you aren't an urban explorer, with a cord going from your smart device in hand to your pocket or backpack where you're storing this, then maybe this scenario isn't one you'll face. But for me it was enough that I'll probably give this one away and go with another power core instead.
